Is it fluorite that the ordinary stone that glows green when the sun shines and the light shines?

*Yes**, if a normal stone glows green in the sun or light, then it is most likely fluorite. The name of fluorite** is due to its characteristics of often emitting blue-green fluorescence under ultraviolet or cathode ray irradiation, and fluorite itself also has bright and changeable colors and complete cleavage properties.

Fluorite and night pearls in nature.

1. Fluorite, also known as fluorite.

It is a mineral whose main component is calcium fluoride (CaF2). Fluorite comes in many colors and can also be transparent and colorless. Transparent and colorless fluorite can be used to make special optical lenses. Fluorite in ultraviolet light.

Or it often emits blue-green fluorescence under cathode ray irradiation, and its name is based on this characteristic. Common colors: green, blue, brown, yellow, pink, purple, colorless, etc.

2. Fluorite luminescence has two kinds: fluorescence and phosphorescence, fluorescence refers to the light source can still be luminous for a short time after the light source is irradiated, phosphorescence fluorite belongs to the internal energy luminescence caused by rare earth ions, and can continue to emit light without external light source supplementation. The phosphorescent is not only the rare and precious night pearl, (this phospho-containing fluorite is very rare in nature), and only this fluorite can be made into a night pearl after careful polishing and processing. Fluorite fluorescence is normal, it does not mean that this is a real night pearl, so it leads to a fluorite ball on the market to make an identification and sell the night pearl.

The luminescence (phosphorescence) mechanism of night pearl is the same as that of rare earth elements.

The electrons are excited by heat or light, and the electrons return to their original positions at night to release light energy, which is called "phosphorescence" in mineralogy.

No.

The mineral comes from volcanic magma, in the process of magma cooling, the gas-water solution separated by the magma contains fluorine, in the process of the solution rising along the fracture, the fluoride ions in the gas-water solution combine with the calcium ions in the surrounding rocks to form calcium fluoride, which is formed after cooling and crystallization. It is found in rocks such as granite, pegmatite, and syenite.

In the Neolithic Age, the Hemudu people in China used fluorite for decoration. The mining and excavation of fluorite originated in ancient Egypt, when people widely used fluorite to make statues and carvings in the shape of scarabs. In ancient Rome, fluorite was widely used as a precious stone in the production of wine glasses and vases, and the ancient Romans even believed that fluorite wine glasses would make people not drunk with a thousand cups.

In 1529 the German mineralogist G. Georg Agricola (G. Agricaola).Agricola) was the first to mention fluorite in his writings, in 1556 he found that fluorite is a mineral with a low melting point in the process of studying fluorite, adding a certain amount of fluorite in iron and steel smelting, not only to increase the furnace temperature, remove sulfur, phosphorus and other harmful impurities, but also to form a eumelt mixture with slag, enhance activity, fluidity, and separate slag and metal.

Fluorite exists in nature that naturally emits light. The reason is that some rare earth elements are mixed in. For example, the British fluorite contains a large amount of yttrium. Causes discoloration. But this kind of fluorite is very rare, at least in the country only exists in legends.

There is also a part of fluorite, which can emit fluorescence under ultraviolet light. However, fluorite from different origins also reacts differently to ultraviolet wavelengths.

However, most fluorites do not observe fluorescence.

Summary. The stone that glows green at night is fluorite. Fluorite is also called noctilucent stone, and some experts point out that the night pearl is actually a fluorite that can emit light, that is, noctilucent stone. Night pearls fluoresce when irradiated by a strong radioactive source.

Is a phone flashlight considered glare?

The mobile phone flashlight is not a strong light, it is a normal light source.

Glows green at night. The light will be stronger after being irradiated with a mobile phone flashlight. It's a stone.

It is fluorite, and the night pearl will fluoresce after being irradiated by a strong radioactive source.

A small garden ball made of fluorite. Is it worth the money?

Worthless, ** around 50 yuan.

It glows at night, and it can be used as a flashlight, and his body looks like a billiards, and it looks transparent, and it's worth much.

It will glow at night, and it can also be used as a flashlight, and his body is like a billiards, which looks transparent, and is worth about 200 yuan.

Hello. Hello.

A stone that glows green when exposed to strong light.

Hello, glad to answer for you. The white stone glows green after being irradiated with light, and Boqing Zheng is the first fluorite It should be fluorite, and the night pearl is a kind of fluorite, it depends on whether your stone will continue to emit light if you don't let the light source irradiate.

Fluorite, oh dear. Is it worth the money?

Valuable oh dear.

It's worth a lot of money.

About 10,000 or so.

Quartz pebbles, the main chemical component is silicon dioxide, followed by a small amount of iron oxide and trace amounts of manganese, copper, aluminum, magnesium and other elements and compounds. The reason for its formation is the broken rock, the edges and corners disappear through long-distance transportation, forming a garden-shaped or oval stone, produced in the places of rivers and rivers in various places, there are many varieties, the stone pattern has strips, stripes, spots, corrugations and irregular curved strips, etc., mostly black, yellow, blue-gray, its shape is mostly round and shaped, the surface is fine and smooth, flat and smooth, the stone is solid, most of them are irregular blocks, with wax or glass luster, translucent. It can cut the glass and leave scratches, no odor and light odor, and it is not easy to heat when it is quickly rubbed.
